67 | * Strictly speaking, this will lead to invalid C when | |

70 | * which will expand to | |
71 | * static const char s[] = ("FOO"); | |

73 | * be without the parentheses. But many compilers do accept it | |

82 | * (notice the missing comma on one of the lines) by forcing | |
83 | * a compilation error, because parenthesised ("one") ("two") | |
